how do people isolate specific audio tracks from a file without access to the master tapes? Such as when someone makes an isolated vocal or bass track of a song or when someone makes a mashup of instruments from one song with the vocals from another.

If the source is a stereo 2 track, then the answer is that much like a baked cake, you can’t extract just the eggs out, or just the flower out. You can however, try and filter out certain frequencies to try and reduce the other tracked items in the mix, but it doesn’t sound very good. Remixes often times use the source instrumentals or vocal tracks as well, it’s not uncommon for that to be done.
